Unit:
Forces and Motions 7.P.1.1-7.P.1.4 / Q1Q2Q3Q4
Common Core and/or Essential Standards:
  1. Understand motions.
  2. The effects of forces on motion.
  3. Graphical representations of motion.
/ Transfer: Students will be able to independently use their learning to…
Use physical laws to design and engineer mobile devices.
Read and interpret graphs using motion, position, time and speed.
Appraise the effectiveness of a vehicle’s design to its performance and safety.
Predict the trajectory of moving objects.
Meaning
Understandings: Students will understand that…
Motion behaves according to laws. (Newton’s Laws)
An objects motion can be described by its position, direction, and speed.
Students will understand the effects of balanced and unbalanced forces.
Creating and interpreting graphs to show changes in position, time, speed and variable motion.
Balanced and unbalanced forces effect movement of objects. / Essential Question(s):
  1. How are forces of an object related to its motion?
  2. What are various ways moving objects will behave?
  3. How do the changes in forces affect position?
  4. Compare balanced and unbalanced forces?
  5. What is Inertia?
  6. What is force?
  7. What do we mean by “equal but opposite” reaction?
  8. What are Newton’s 3 laws of motion?

Acquisition
